Casual Brothers and Reverb Publishing invite players to kick off their Halloween celebration with the ultimate co-op party game that was recently Greenlit on Steam, Orc Attack: Flatulent Rebellion. Orc Attack: Flatulent Rebellion is a 1-4 player cooperative gas-and-slash action game that is available now on the Xbox Live® online entertainment network from Microsoft and PlayStation®Network in North America and Europe and is coming soon to Steam.

“We are thrilled about being Greenlit and couldn’t have done it without the help of our awesome fans,” said Nacho Sanchez, co-developer, Casual Brothers. “Being Greenlit on Steam is going to allow all players to enjoy the humorous and gassy world of Orc Attack: Flatulent Rebellion.”

Fart or die in this gas-and-slash action game, where fun-loving Orcs battle pollution spreading Humans in a humorous fantasy setting. Orcs have become victims of brutal Human expansion, as they are carelessly poisoning the environment. Now, four trained Orc heroes are retaliating with a not-so-silent yet very deadly plan. In either single-player or up to four-player co-op, gamers will take on the role of Orcs, each wielding a unique gaseous ability, and then take the fight to the Humans in a stinky, fart-filled romp.

Developed by Casual Brothers, Orc Attack: Flatulent Rebellion is rated T and is available now for download on Xbox Live and PlayStation Network and is coming soon to Steam.
